How the Sat-email-Decoder
Works
Warning:
Downloaded files may contain viruses, spyware, Trojan horses and other malicious code, which may
gravely endanger your system. WAVECOM explicitly declines any liabilities for the use of this application,
and strongly advises users to ensure that an updated anti-virus and malware checking application is installed and enabled. The user may additionally consider physically disconnecting the system on which this
application is installed from a local network. If an alert or warning is received from your anti -virus application, follow the instructions given to remove or neutralize the threat.
The W-Sat-email-Decoder takes as its input a session file and the corresponding text files, as produced by
a WAVECOM decoder, or any text file from an external source containing emails. Before beginning decoding, it prescans the file to make sure that the input data is not corrupt. After prescan it does protocol decoding and possible decompression, the email(s) and possible attachment(s) are output as files (see the
message flow below).
The output files may themselves be encoded or compressed. In this case external applications must be
used to decode and/or decompress the files. This procedure is shown in the path diagram above in dashed
lines and grayed-out boxes. External processing may have to be repeated until legible output is produced.
The user should be aware that messages may be encoded using methods such as UUEncode, Base64 and
TNEF. Such messages must also be decoded by an external application.
The W-Sat-email-Decoder will decode the main message protocols encountered on satellite and other
communication links. These protocols reside on Layer 2, the data link layer.
8 How the Sat-email-Decoder Works WAVECOM Sat email Decoder W-Sat-email-Decoder V2.3.1
User Interface
The W-Sat-email-Decoder consists of a menu bar a window with three panes,
Input File List
File Viewer
Decoded File List
The Input File List displays a record of information for each of the files(s) loaded using the File Menu.
File View displays a hex and text dump of the file selected in the Input File List.
The Decoded File List contains a list of decoded files.
Menu bar
The main menu bar contains four menus.
File Menu
Click Open file… to load a single file into the Input File List.
Click Open directory… to load a complete directory containing an optional session file produced by a
WAVECOM decoder.
Click Save as … to save one or more files.
Click Exit to exit the W-Sat-email-Decoder. When attempting to close the ED, the user is asked
If saving the decoded data is not required press “No”.
If saving the decoded data is required press “Yes”, then select one, more or all files in the Input File List
and from the File Menu select Save as … to open a directory browser. In the browser select an existing
folder or create a new folder where the decoded data should be stored.
WAVECOM Sat email Decoder W-Sat-email-Decoder V2.3.1 User Interface 9
Edit Menu
Click Select All to select all files in the Input File List.
Click Decode to decode all selected files.
Tools Menu
Click Preferences… to select all files in the Input File List.
Click Enable Auto Mode to start the automatic decoding of files placed into the input decode all selected
files.
Preferences
Data sources (auto mode) define folders which will be used as a data source for automatic decoding if
Auto Mode is enabled.
Output folder decoded data are placed in this folder.
Clean up output folder on exit. The defined output folder is cleaned up on program exit.
Help Menu
Through the help menu a help file and information on W-Sat-email-Decoder is accessible.
Input File List
The Input File List is the entry point into the W-Sat-email-Decoder and displays a record of information
for each of the files(s) loaded using the File Menu. Double-clicking a record will start an attempt to de-
termine the mail system and decode the file (the “Mail System” column will be set to “Unknown” before
this attempt). The columns labeled “Termination”, “Mail System” and “Status” displays the results of the
operations (see end of section for a detailed list). At the same time the raw input file is loaded into the
10 User Interface WAVECOM Sat email Decoder W-Sat-email-Decoder V2.3.1
File Viewer and finally, if decoding was successful, a list of decoded output files is displayed in the Decoded File List.
In the example below, a mail file captured from a decoder with serial number 606029620 has been determined as using the GlobeWireless mail system and successfully decoded. The compressed file contained
an email message (Mail_1.txt) and an attachment (4th Quarter CORINTH Stores.zip).
If an input file is selected clicking Save as… in the File Menu opens a file browser, allowing the user to
save the selected files under another name and path.
Right-clicking one or more selected files displays an option Open output folder… Left-clicking this item,
allows the user to open the directory where the decoded and decompressed output files for the selected
input file are saved. In the example below the file described earlier, has been decompressed and its components separated into individual files:
- A decoded and decompressed mail message file (Mail_1.txt)
- A decoded and decompressed attachment (4th Quarter CORINTH Stores.zip)
- A text file containing all mail messages (0000001800000018_Pass1.txt)
- A binary file containing the captured, 7z-compressed file without protocol and packet overhead
(headers, CRC etc.) (0000001800000018_Pass1.7z)
- A MetaData.xml file containing various additional information.
WARNING: Depending on your anti-virus application, during decoding of an input file a warning message
like this may be displayed by your anti-virus and malware protection application.

You are strongly advised to follow the instructions given.
Output files are saved in sub-folders in the selected data folder. The sub-folder names are constructed as
<decoder_serial_number>_<yyyymmdd>_<hhmmss>.
The decoded files are saved in a number of ways depending on the email system:
If the decoded mail system transmits messages and attachments as individual messages, the out-
put files are saved under their original names with a preceding number, e.g. 01_255996071.txt
starting with 01 for the first decoded file
If the decoded mail system transmits messages and attachments consolidated into one file, the
application will attempt to decompress the file and to save the individual messages and attachments under their original file names, otherwise a generic name, Mail_<number>.txt is used
The Input File List is divided into a number of columns,
File Viewer
The File Viewer will display a selected input or output file in a hexadecimal file viewer. The leftmost column is a hexadecimal byte counter, the center column displays the file in hexadecimal notation, and the
rightmost column displays the file contents in printable ASCII. The viewer does not allow the user to edit
the file.
Decoded File List
The Decoded File List displays the output file(s) if decoding was successful. Left-clicking on a file name
will display the file in the File Viewer. Left-clicking the file name will load the file into the File Viewer
and display this message,
12 User Interface WAVECOM Sat email Decoder W-Sat-email-Decoder V2.3.1

Input data format
The Decoders now support two formats:
Data stream extracted from INMARSA-B, INMARSA-M or INMARSAT-mM frames
Raw data from Inmarsat-B-HSD (ISDN)
INMARSAT-B, INMARSAT-M or INMARSAT-mM
Use this format for INMARSAT-B, INMARSAT-M or INMARSAT-mM low speed data. The expected format is
the data extracted from the HDLC I-Frames in the correct order and without duplicates. In other words,
the same data stream a user of the satellite services sends and receives.
INMARSAT-B-HSD
Use this for ISDN data (SAT-B-HSD). The format consists of the raw contents of the data frames, without
signaling units.
Metadata output format
The metadata output is not yet fixed. The following format description is based on the XML output by the
GUI. For now, not all decoders are able to write metadata.
The XML files created by the GUI are structured as follows:
<MetaData>
<Transmission>
<!-- This part is filled by the GUI. Decoders do not use it. -->
</Transmission>

External Applications
If the output file is itself a compressed or encoded file, the user must launch an external application as described above to decode or uncompress the file. The user may wish to use the information below as a
guide on how to further process such files.
Encoding
Many Uuencode, Base64 and similar decoding tools may be found on the Internet. WinZip will decode
most encodings, as well as performing decompression.
TNF files (Transport Neutral Encapsulation Format) may be read using freeware such as Winmail Opener,
Winmail Reader or tnef2win. Be aware that the TNEF format in addition to the publicly known and described Microsoft tags allows private tags, which are used by certain email systems and which the freeware readers will not decode.
Compression
A number of freeware decompressors are available from the Internet, i.e. WinRAR, 7zip, etc. Furthermore,
source code for most methods is available in case you wish to roll your own de-compressor.

Glossary of Terms
active window
The window on the screen where the next action will take place. The active window is indicated by a colored title bar and border.
AF-IN
The AF input has a range of 0 – 16.000 Hz. This input should be used when the source is an AF output
(line or speaker) or a 12.0 or 12.5 kHz IF output used in professional digital recorders.
alert
A warning or notice of an error in the form of a message, a sound from the computer's speaker, or both.
AMBE
Advanced Multi-Band Excitation speech coding.
ANSI
An acronym for the American National Standards Institute, an organization that sets standards for a variety of programming languages and systems.
AOR
Atlantic Ocean Region.
APC
Adaptive Predictive Coding.
ARQ
Automatic repeat request (ARQ) (or automatic repeat-query) is an error-control method for data transmission which uses acknowledgements and requests to achieve reliable data transmission over an unreliable
service. An acknowledgement is a message sent by the receiver to the transmitter to indicate that it has
correctly received a data frame or packet. A request is a message sent by the receiver to the transmitter
to indicate that the sender has to re-transmit the frame/packet; if the sender does not receive an
acknowledgement before a timeout, it usually re-transmits the frame/packet until it receives an acknowledgement or exceeds a predefined number of re-transmissions.
ASCII
An acronym for American Standard Code for Information Interchange, pronounced "ASK-ee." It is a code
in which the numbers from 0 to 127 stand for letters, numbers, punctuation marks and other characters.
ASCII code is standardized to facilitate transmitting text between computers or between a computer and a
peripheral device.
Baud Rate
The speed in a 2FSK transmission. The duration of a bit is 1/Baud. At 50 Baud a bit is 20ms long.
WAVECOM Sat email Decoder W-Sat-email-Decoder V2.3.1 Glossary of Terms 23
The speed is given as the channel speed in Bauds. For two level modulation types this equals the raw us er
bit rate, for four level s the bit rate is doubled, for eight levels it is tripled etc.
Broadcast
Public or private radio station transmitting music, news...
Buffer
A temporary holding area in the computer's memory where information can be stored. In editing, it is an
area in memory where cut or copied data is held, sometimes called the clipboard. See also: clipboard and
type-ahead buffer.
Clipboard
The holding place for what you last cut or copied; a buffer area in memory. Information contained on the
clipboard can be inserted (pasted) into other documents and other WINDOWS applications.
Context sensitive
Able to perceive the situation in which an event occurs. For example, context sensitive help presents information specific to the particular task you are performing, rather than presenting just a general list of
commands.
Control key
A specific key, usually abbreviated as "Ctrl", that produces control characters when used in combination
with character keys.
CRC
A cyclic redundancy check (CRC) is an error-detecting code designed to detect accidental changes to raw
data, and is commonly used in digital data transfer and storage. A CRC-enabled protocol calculates a
short, fixed-length binary sequence, known as the check value or improperly the CRC, for each block of
data to be sent or stored and appends it to the data, forming a codeword. When a codeword is received or
read, the device either compares its check value with one freshly calculated from the data block, or equivalently, performs a CRC on the whole codeword and compares the resulting check value with an expected
residue constant. If the check values do not match, then the block contains a data error and the device
may take corrective action such as requesting the block be sent again, otherwise the data is assumed to
be error-free (though, with some small probability, it may contain undetected errors; this is the fundamental nature of error-checking).
CRCs are so called because the check (data verification) code is a redundancy (it adds zero information to
the message) and the algorithm is based on cyclic codes. CRCs are popular because they are simple to
implement in binary hardware, are easy to analyze mathematically, and are particularly good at detecting
common errors caused by noise in transmission channels. As the check value has a fixed length, the function that generates it is occasionally used as a hash function.
Database management system
(DBMS) - A software system for organizing, storing, retrieving, analyzing and modifying information.
Default button
The push button with a bold border in dialogues. The default button often has a dotted-line border around
the button name. The default button is chosen when you press "Enter" (or Ctrl+Enter depending on your
configuration).
24 Glossary of Terms WAVECOM Sat email Decoder W-Sat-email-Decoder V2.3.1
Default font
Used font if no other font is defined.
DIS
The DIS input (Discriminator) has a range of 0 – 20 kHz. This input is supported by a few VHF-UHF re-
ceivers and facilitates the reception of ”Direct FSK” signals like POCSAG or PACKET-9600. The advantage
of this input is the easy handling. Only the gain has to be adjusted. There is no need for an adjustment of
the center or the translation frequency. DIS is only released for ”Direct FSK” modes.
Disable
To make an item unavailable for use. Disabled items reflect the WINDOWS color settings for disabled
commands, and generally appear dimmed and cannot be chosen.
EOD
End-Of-Data.
Error message
A message displayed to tell the user about an error or problem in the execution of a program or in the user's communication with the system. An error message is often accompanied by a beep.
EXT-DEM-IN
The EXT-DEM-IN input must be used if an external demodulator is to be connected. The minimum input
level is TTL level (LO = 0 V, HI = +5 V) and the maximum is RS-232C level (LO = -12 V, HI = +12 V).
Note that utilizing this facility will disable certain W51PC functions. Thus this input should be employed for
special purposes only.
FDX
Full duplex.
FEC
Forward error correction (FEC) is error control methode for data transmission, whereby the sender adds
redundant data to its messages, also known as an error-correction code. This allows the receiver to detect
and correct errors (within some bound) without the need to ask the sender for additional data. The advantages of forward error correction are that a back-channel is not required and retransmission of data
can often be avoided (at the cost of higher bandwidth requirements, on average). FEC is therefore applied
in situations where retransmissions are impossible (traffic lists, broadcasts).
FFSK
Fast Frequency Shift Keying.
FFT
Fast Fourier Transform.
File type
The categories of files specified by file extensions: APP, DBF, PRG, CDX, FRX, and so on.
WAVECOM Sat email Decoder W-Sat-email-Decoder V2.3.1 Glossary of Terms 25
GFSK
Gaussian Frequency Shift Keying.
GUI
Graphical User Interface.
HDX
Half duplex.
Hot key
An underlined letter in a menu or dialogue that you can type to immediately choose an item.
IF-IN-10.7
The IF-IN-10.7 input has a range of 10.685–10.715 MHz (or 21.385 – 21.415 MHz). This IF is common for
VHF-UHF receivers.
IF-IN-21.4
The IF-IN-21.4 input has a range of 21.385–21.415 MHz. This IF is common for VHF-UHF receivers.
IF-IN-VAR
The IF-IN-VAR has a range of 14 kHz–1.5 MHz. Most receiver IF’s are within this range.
IMBE
Improved Multi-Band Excitation speech coding.
Insert mode
The default text-editing mode in which any character you type is inserted at the cursor position and the
text to the right of the cursor is shifted to the right.
IOR
Indian Ocean Region.
IQ
In-phase Quadrature. Used to denote the complex format on which the RF data is processed and stored.

SELCAL
Selective call systems are an efficient supplement to voice traffic. One method was the so-called singletone-mode using five different tone frequencies, another one the two-tone-modes, where the call number
is transmitted as frequency combinations.
Developments led to the five-tone-sequence systems. The five digits are often divided into two groups.
The first digits work as radio net flags, the last three digits are user call numbers.

Lower frequency
Higher frequency
The entire call number is transmitted by consecutive tones in decade sequence. When two identical digits
are to be transmitted consecutively, then an eleventh frequency is used as a repetition identifier. If there
more than two identical digits are to be transmitted the repetition tone is appended to the digit tone (e.g.
22222 is transmitted as f2 fw f2 fw f2, where f2 is the tone for “2” and fw is the repetition tone).
In most systems the accuracy of the single frequencies has to be within +1/-1.5% of the nominal value.
Modifications of the tone allocation and tone duration has led to numerous systems despite many standards.
Only the EURO (EuroSignal) system uses six consecutive tones. The worldwide telephone signaling standard DTMF mode transmits two simultaneous tones.
